  <p>Return the output from free function <a href="../../../reference/functions/failure.html" class="api-reference"><code>auto failure(T &amp;&amp;, ...)</code></a>
 containing a copy of any errored and/or excepted state. The error and/or exception state is accessed using <a href="../../../reference/types/basic_outcome/assume_error_lvalue_const.html" class="api-reference"><code>const error_type &amp;assume_error() const &amp; noexcept</code></a>
 and <a href="../../../reference/types/basic_outcome/assume_exception_lvalue_const.html" class="api-reference"><code>const exception_type &amp;assume_exception() const &amp; noexcept</code></a>
.</p>

<p><em>Requires</em>: Always available.</p>

<p><em>Complexity</em>: Whatever that of <code>error_type</code>&rsquo;s and/or <code>exception_type</code>&rsquo;s copy constructor is.</p>

<p><em>Guarantees</em>: None.</p>
